Chemicals and drugs

The use of chemicals in micro irrigation systems requires a deep understanding of the properties and composition of water, added chemicals, the possibility of interaction of various chemicals with each other, and based on this, a clear statement of goals is required to be achieved.

Micro-irrigation has tremendous advantages in terms of chemical dosage. The competent addition of nutrients supplied to the root system of plants with irrigation water, subject to the exact dosage of chemical components corresponding to the needs of the plants, significantly increases the efficiency of the use of fertilizers and water, helps to increase yields and product quality, and also reduces the total cost per unit of production. Systemic pesticides and some fumigants can be used in micro-irrigation with very high efficiency.

When using chemicals and plant protection products in irrigation systems, safety rules must be strictly followed. This refers to the design of the irrigation system, which provides for a number of technical solutions that provide protection against the ingress of aggressive and toxic substances into the environment and water sources, as well as reliable protection of maintenance personnel.

The concentration of additives in micro irrigation systems

The concentration of additives should not exceed 0.1%. Chlorine and pesticides should preferably be added at even lower concentrations. In addition, you need to make sure that all chemicals added at the same time are compatible with each other and will not lead to undesirable consequences. Certain combinations of chemicals such as calcium nitrate and phosphoric acid will result in immediate insoluble precipitation and can lead to serious problems. The use of emulsion and powder water-insoluble pesticides may require special technical solutions, such as the installation of special emulsifier tanks or mechanical mixers, to create homogeneous mixtures and reduce the likelihood of failure. Such substances can be used only in case of urgent need.

After the introduction of chemicals, the irrigation water must be filtered. Fertilizers and chemicals other than chlorine should never remain in the system if the system is not working. Pesticide and fertilizer additions should be done in small, frequent doses, which are applied at regular irrigation intervals that are consistent with planned irrigation rates. The recommended regime is one quarter of the time – clean water, half of the watering time – watering with chemical additives and the last quarter of the watering cycle – clean water.
